Upgrade urgency HIGH: This release fixes several Redis stability issues.
Dear Redis users, this release includes a number of fixes for bugs that may
result in Redis crashing in special conditions (not normal usage, but specific
artificial conditions), fixes to certain Redis behaviors especially around
Redis streams, and finally a set of new APIs for Redis Modules.
Specifically:
* Hyperloglog different coding errors leading to potential crashes were fixed.
* A replication bug leading to a potential crash in case of plain misuse of
handshake commands was fixed.
* XCLAIM command incrementing of number of deliveries was fixed.
* LFU field management in objects was improved.
* A potential overflow in the redis-check-aof was fixed.
* A memory leak in case of API misuse was fixed.
* ZPOP* behavior when count is 0 is fixed.
* A few redis-cli --cluster bugs were fixed, plus a few improvements.
* Many other smaller bugs.
We suggest to upgrade Redis, especially in case your instance is facing
untrusted users (for instance Cloud providers) because several of these
bugs could result in unwanted crashes.
